Gardaí have launched an investigation into the conduct of anti-mask protestors on the Luas Red Line yesterday.

The group, who had attended a city-centre rally yesterday against the lockdown and mandatory face-mask regulations, told other passengers to take off their masks whilst on board the Luas.

Transdev, the Luas operator, said it has passed on CCTV footage to aid Gardaí in their investigation.

A statement by An Garda Síochána explained that officers had accompanied the protest from the Garden of Remembrance to a HSE office in Dublin 8, but were not present when the alleged incident occurred.

“An Garda Síochána will investigate this matter and the advice of the Director of Public Prosecutions will be sought in respect of any further actions to be taken,” it said.

“Gardaí are aware of videos circulating on social media showing a number of individuals on public transport not complying with public health regulations,” it said.

The Garda Press Office said that Gardaí cannot enforce the face-mask regulation on public transport, but can act “after a report or complaint by a ‘relevant person’ has been made.”

The video was streamed on Facebook by organisers of “the Freedom Rally” protest and showed the group chanting “End The Lockdown” and other songs on the tram to the annoyance of some, with one woman shouting “put on a f**king mask”.
